The velocity of a particle is given by v...

The velocity of a particle is given by `v=(4t^(2)-4t+5)m//s` where t is time in seconds. Find its acceleration at t=4 second.

Text Solution

Verified by Experts

The correct Answer is:
C
Time to fall `=sqrt((2xxh)/(g))`
Range = Horizontal velocity `xx`
`x=sqrt(2gh)xxsqrt((2h)/g)=2h`
